Synthesis of p-substituted tetraphenylporphyrins and corresponding ferric complexes with mixed-solvents method

Abstract: By using mixed-solvents method, five kinds of p-substituted tetraphenylporphyrin compounds [T(p-R)PPH 2 , R = NO 2 , Cl, CH 3 , OCH 3 , OH] were synthesized by the condensation of p-substituted benzaldehyde with pyrrole in mixed solvents (propionic acid, acetic acid and nitrobenzene), and corresponding ferric complexes [T(p-R)PPFe III Cl] were synthesized in dimethylformamide. The above free base porphyrins were obtained in 30%-50% yields, metalation yields were up to 90% and total yields of ferric complexes w… Show more

“…Tetraphenylporphrin zinc (Zn-Por) was synthesized according to the previous literature [36] as shown in Scheme S1. TPP (1 g, 1.6 mmol) prepared using the Adler method as in previous work [29] and Zn(Ac) 2 2H 2 O (1.4 g, 6.4 mmol) were dissolved in chloroform (CHCl 3 ) (40 mL).…”

“…Then by adding excess 1-bromooctane to H 2 TPyP at refluxing temperature, tetrakis(Noctyl-4-pyridinium)-porphyrin bromide, H 2 TPyPC 8 Br 4 , was synthesised in nearly quantitative yield. 28 [30][31][32] A total of five water-soluble, magnetic, ionic substituted tetrapyridyl metalloporphyrins were prepared in yields above 75%.…”

“…В работе был использован метод монопиррольной конденсации и изучены 2 подхода при проведении этой реакции: в смеси органических растворителей [7] и в водно-мицеллярной среде. [8] Как известно, образование мезо-окси-фенилпорфиринов обычно протекает с низкими выходами и сопровождается большим количеством трудноотдели-мых примесей.…”

“…[10] Наиболее же перспективным и широко используемым в настоящее время методом получения мезо-оксифенилпорфиринов является гидролиз легко доступных мезо-метоксифенилпорфиринов с использо-ванием мягкого деметилирующего агента -трибромида бора. [11] Недавно в работе [7] сообщалось об эффективном синтезе серии п-замещенных тетрафенилпорфиринов, в т.ч. окси-производных, по методу Адлера с использо-ванием смеси нитробензола с пропионовой и уксусной кислотами.…”
